Description

The Dwyer Instruments RHPX-2LHAB-00 Humidity and Temperature Transmitter is engineered for precision environmental monitoring in critical indoor applications. It utilizes a high-stability capacitive polymer sensor for humidity and a passive 10 kΩ Type II thermistor for temperature, delivering reliable data for building energy management and HVAC control.

Housed in a large, robust IP66 enclosure, the transmitter is protected against dust and water jets. The inclusion of a factory-installed HDPE filter and a solar radiation shield ensures long-term measurement stability by minimizing contamination and thermal radiation effects. Its selectable analogue output (4–20mA/0–5V/0–10V) and 10–35 VDC power input provide versatile compatibility with PLCs, DDCs, and data acquisition systems.

Key Features

  • High-Accuracy Sensing: Delivers reliable 0–100% RH and -40°C to 60°C measurements with ±2% RH accuracy.
  • Robust Environmental Protection: IP66-rated large enclosure ensures durability in demanding indoor environments.
  • Integrated Signal Conditioning: Features selectable 4–20mA, 0–5V, or 0–10V analogue outputs for direct PLC/controller interface.
  • Enhanced Measurement Integrity: Factory-installed HDPE filter and solar radiation shield protect sensor for stable, long-term performance.
  • Simplified Installation: Tool-free, wall-mount design with a large enclosure for easy deployment and service.
  • Broad Compliance: UL 2043 compliant for safe use in plenum air spaces.
  • Wide Operating Voltage: Supports 10–35 VDC power supply for flexible system integration.
  • Passive Temperature Sensor: Utilizes a standard 10 kΩ Type II thermistor for easy replacement and compatibility.

Frequently Asked Questions

What are the available analogue output options for the RHPX-2LHAB-00 transmitter?

The transmitter features a selectable analogue output, configurable for either a 4–20 mA current loop, a 0–5 VDC voltage signal, or a 0–10 VDC voltage signal. This flexibility allows for direct compatibility with most PLCs, DDC controllers, and data acquisition systems without requiring additional signal conditioners.

How is the temperature sensor configured, and can it be replaced?

The unit integrates a passive 10 kΩ Type II thermistor for temperature measurement. This is a standard, two-wire resistive sensor, making it straightforward to interface and replace if necessary, ensuring long-term maintainability within your system.

What is the purpose of the factory-installed HDPE filter and solar shield?

The HDPE filter protects the humidity sensor from dust and particulate contamination, preserving accuracy. The solar radiation shield minimizes the effects of radiant heat on the temperature sensor, ensuring the reported air temperature is accurate and not influenced by direct sunlight or nearby hot surfaces.

What are the power requirements for this transmitter?

The transmitter operates from a 10–35 VDC power supply. This wide input range provides compatibility with common 24 VDC industrial power systems and offers flexibility for installations where voltage regulation may vary.

Is this transmitter suitable for installation in plenum spaces?

Yes, the Dwyer Instruments RHPX-2LHAB-00 is UL 2043 compliant, certifying it for safe installation in plenum air handling spaces. This makes it ideal for HVAC applications where equipment must meet specific fire safety and smoke emission standards.
